WARNING: Field wiring must comply
with local and national electric codes.
WARNING: Power to the unit must be
within the operating voltage range
indicated on the unit nameplate or on
the performance data sheet.
NOTE: Operation of unit on improper
line voltage or with excessive phase
imbalance will be hazardous to the unit,
constitutes abuse and may void the
warranty.
